Ear Thermometer

Project Background:

Common infrared sensor applications can be divided into medical, industrial, and consumer applications, such as ear Ear thermometer, forehead Ear thermometer, industrial thermometer, infrared thermometer, etc.

Design Research:

In the application of ear Ear thermometer, it is necessary to pay attention to the temperature rise effect of infrared sensor entering the ear, the connection mode of wave guide tube and sensor, etc. In the application of infrared thermometer, it is necessary to pay attention to the distance between the object to be measured and the focusing distance of the lens.

Solution:

The infrared sensor is used as the source of temperature signal acquisition, which is converted into resistance and micro voltage signal transmission, and then the temperature data is obtained by single chip microcomputer measurement, calculation and digital transmission.
